。[Scope of Claim for Utility Model Registration] A nut is attached to the outer periphery of a screw shaft via a steel ball, an outer ring is attached to the outer periphery of the nut, and raceway grooves are provided on opposing surfaces of the outer periphery of the nut and the inner periphery of the outer ring. In a ball screw with a support bearing in which a rolling element is rotatably interposed between, the raceway groove is formed into a substantially right-angled V-shaped groove, and
The rolling elements are rollers, and adjacent rollers are arranged alternately orthogonally;
A ball screw with a support bearing, comprising a pair of bearing rings in which the outer ring is divided into two parts in the axial direction, and a preload can be applied to the roller by narrowing the axial distance between the bearing rings.
